     5.3(d)(i), the holders of Class A Common Stock shall be entitled to receive
     out of the proceeds of such Liquidation Event, before any payment shall be
     made to the holders of any capital stock ranking on a Liquidation Event
     junior to the Class A Common Stock, an amount per share of Class A Common
     Stock equal to the Original Cost of such share of Class A Common Stock (the
     "CLASS A COMMON LIQUIDATION PREFERENCE AMOUNT"). If, upon the consummation
     of any Liquidation Event, the proceeds of such Liquidation Event available
     for distribution to the Corporation's stockholders are insufficient to pay
     the holders of Class A Common Stock the full Class A Common Liquidation
     Preference Amount, the holders of Class A Common Stock shall share ratably
     in any distribution of proceeds based upon the number of

                                                                             -9-

     shares of Class A Common Stock held by each such holder. Upon the
     consummation of any Liquidation Event, after payment shall have been made
     to the holders of Class A Common Stock of the full Class A Common
     Liquidation Preference Amount pursuant to this SECTION 5.2(d), the holders
     of Common Stock shall be entitled to receive out of the proceeds of such
     Liquidation Event an amount per share of Common Stock equal to the Original
     Cost of such share of Common Stock (the "COMMON LIQUIDATION PREFERENCE
     AMOUNT") PARI PASSU with the payment of the Series B Liquidation Preference
     Amount. If, upon the consummation of any Liquidation Event, the proceeds of
     such Liquidation Event available for distribution to the Corporation's
     stockholders are insufficient to pay the holders of Common Stock the full
     Common Liquidation Preference Amount and the holders of Series B Preferred
     Stock the full Series B Preferred Liquidation Preference Amount, the
     holders of Common Stock and Series B Preferred Stock shall share ratably in
     any distribution of proceeds based upon the number of shares of Common
     Stock and/or Series B Preferred Stock held by each such holder (such
     calculation to be made on an as-converted basis as if the Common Stock and
     the Series B Preferred Stock were a single class).

            (ii)  Upon the consummation of a Liquidation Event, after payment of
     the Series A Preferred Liquidation Preference Amount, the Class A Common
     Liquidation Preference Amount, the Common Liquidation Preference Amount and
     the Series B Preferred Liquidation Preference Amount in accordance with the
     terms hereof, the holders of Common Stock and the holders of Class A Common
     Stock shall share ratably in the remaining proceeds of such Liquidation
     Event, if any, based upon the number of shares of Common Stock and/or Class
     A Common Stock held by each such holder (such calculation to be made as if
     the Common Stock and the Class A Common Stock were a single class).

5.3  PREFERRED STOCK.

        (a) VOTING RIGHTS. Except as set forth herein or as otherwise required
by Applicable Law, neither the Series A Preferred Stock nor the Series B
Preferred Stock shall be entitled or permitted to vote on any matter required or
permitted to be voted upon by the stockholders of the Corporation.
Notwithstanding the foregoing, the holders of each series of Preferred Stock
shall have the right to vote as a separate series on any amendment of this
SECTION 5.3(a) and on any amendment, repeal or modification of any provision of
this Certificate of Incorporation that adversely affects the powers,
preferences, or special rights of the shares of such series of Preferred Stock.

        (b) DIVIDENDS. The holders of Preferred Stock shall not be entitled to
receive any dividends from the Corporation with respect to the Preferred Stock;
PROVIDED, HOWEVER, that if any dividend is declared and paid on any share of
Common Stock or Class A Common Stock, each holder of shares of Preferred Stock
shall be entitled to receive such dividend with respect to each share of
Preferred Stock held by such holder.

                                                                            -10-

        (c) CONVERSION.

              (i) OPTIONAL CONVERSION OF SERIES A PREFERRED STOCK INTO CLASS A
     COMMON STOCK. Each holder of Series A Preferred Stock shall have the right,
     at such holder's option and in accordance with the procedures set forth in
     SECTION 5.4, immediately prior to the consummation of either a QPO or a
     Liquidation Event, to convert, without the payment of any additional
     consideration, any or all shares of Series A Preferred Stock held by such
     holder into that number of fully paid and nonassessable shares of Class A
     Common Stock equal to the quotient obtained by dividing (x) the aggregate
     Original Cost of such shares of Series A Preferred Stock, by (y) the
     Applicable Series A Conversion Price. The conversion price (as applicable,
     the "APPLICABLE SERIES A CONVERSION PRICE") per share at which shares of
     Class A Common Stock shall be issuable upon conversion of Series A
     Preferred Stock shall initially be equal to (1) the QPO Price, in the case
     of conversion immediately prior to a QPO, or (2) $1.00 (the "SERIES A
     LIQUIDATION EVENT CONVERSION PRICE"), in the case of conversion immediately
     prior to a Liquidation Event (which Series A Liquidation Event Conversion
     Price shall be subject to adjustment from time to time as set forth in
     PARAGRAPH (iv) below). The Corporation shall give the holders of Series A
     Preferred Stock reasonable prior notice of a QPO or Liquidation Event,
     including the price and material terms and conditions thereof, in order to
     provide the holders of Series A Preferred Stock reasonable opportunity to
     consider whether to convert the shares of Series A Preferred Stock held by
     them into shares of Class A Common Stock in connection with such QPO or
     Liquidation Event. If the price or material terms or conditions of such
     transaction thereafter change, the Corporation shall promptly deliver
     written notice to the holders of Series A Preferred Stock specifying such
     changes.

             (ii) MANDATORY CONVERSION OF SERIES B PREFERRED STOCK INTO COMMON
     STOCK. Immediately prior to the consummation of a QPO (if the proviso to
     SECTION 5.3(e)(i) is applicable to such QPO or the Requisite Series B
     Holders otherwise elect not to have shares of Series B Preferred Stock
     redeemed pursuant to SECTION 5.3(e)(i)), each share of Series B Preferred
     Stock then outstanding shall, without any action on the part of the holders
     thereof, be deemed automatically converted, without the payment of any
     additional consideration, into that number of fully paid and nonassessable
     shares of Common Stock equal to the sum of (1) the quotient obtained by
     dividing (x) the Original Cost of such share of Series B Preferred Stock by
     (y) the QPO Price, PLUS (2) the Participation Component Shares.

            (iii) OPTIONAL CONVERSION OF SERIES B PREFERRED STOCK INTO COMMON
     STOCK. Each holder of Series B Preferred Stock shall have the right, at
     such holder's option and in accordance with the procedures set forth in
     SECTION 5.4, immediately prior to the consummation of a Liquidation Event,
     to convert, without the payment of any additional consideration, each share
     of Series B Preferred Stock held by such holder into that number of fully
     paid and nonassessable shares of Common Stock equal to the sum of (1) the
     quotient

                                                                            -11-
<Page>

     obtained by dividing (x) the Original Cost of such share of Series B
     Preferred Stock by (y) $1.00 (the "SERIES B LIQUIDATION EVENT CONVERSION
     PRICE") (which Series B Liquidation Event Conversion Price shall be subject
     to adjustment from time to time as set forth in PARAGRAPH (iv) below), PLUS
     (2) the Participation Component Shares. The Corporation shall give the
     holders of Series B Preferred Stock reasonable prior notice of a
     Liquidation Event, including the price and material terms and conditions
     thereof, in order to provide the holders of Series B Preferred Stock
     reasonable opportunity to consider whether to convert the shares of Series
     B Preferred Stock held by them into shares of Common Stock in connection
     with such Liquidation Event. If the price or material terms or conditions
     of such transaction thereafter change, the Corporation shall promptly
     deliver written notice to the holders of Series B Preferred Stock
     specifying such changes.

             (iv) ADJUSTMENT OF LIQUIDATION EVENT CONVERSION PRICES. The
     Liquidation Event Conversion Price with respect to any series of Preferred
     Stock shall be subject to adjustment from time to time as follows:

                  (A)  If the Corporation shall, at any time or from time to
        time, after the applicable Original Issuance Date, issue or be deemed to
        have issued any shares of Common Stock (other than pursuant to any
        Equity Incentive Plan or with respect to Excluded Stock), without
        consideration or for a consideration per share less than the Liquidation
        Event Conversion Price in effect with respect to such series of
        Preferred Stock, then, immediately prior to the issuance of such shares
        of Common Stock, the Liquidation Event Conversion Price in effect with
        respect to such series of Preferred Stock immediately prior to each such
        issuance shall forthwith be lowered to a price equal to the quotient
        obtained by dividing:

                       (1)  an amount equal to the sum of (x) the total number
              of shares of Common Stock outstanding (including any shares of
              Common Stock deemed to have been issued pursuant to SUBCLAUSE (3)
              of CLAUSE (B) below) immediately prior to such issuance,
              multiplied by the Liquidation Event Conversion Price in effect
              with respect to such series of Preferred Stock immediately prior
              to such issuance, and (y) the consideration received by the
              Corporation upon such issuance (or deemed issuance, as the case
              may be); by

                       (2)  the total number of shares of Common Stock
              outstanding (including any shares of Common Stock deemed to have
              been issued pursuant to SUBCLAUSE (3) of CLAUSE (B) below)
              immediately after the issuance of such shares of Common Stock. For
              purposes of this SECTION 5.3(c)(iii), "COMMON STOCK" shall mean
              the Common Stock, the Class A Common Stock and any other class or
              series of capital stock of the Corporation hereafter

                                                                            -12-
<Page>

              authorized that is not limited to a fixed sum or percentage of par
              or stated value with respect to the rights of the holders thereof
              to participate in the dividends or in the distribution of proceeds
              upon any liquidation, distribution or winding up of the
              Corporation.

                  (B)  For the purposes of any adjustment of the applicable
        Liquidation Event Conversion Price pursuant to CLAUSE (A) above, the
        following provisions shall be applicable:

                       (1)  In the case of the issuance of shares of Common
              Stock for cash in a public offering (other than a QPO) or private
              placement, the consideration shall be deemed to be the amount of
              cash paid therefor after deducting therefrom any discounts,
              commissions or placement fees payable by the Corporation to any
              underwriter or placement agent in connection with the issuance and
              sale thereof;

                       (2)  In the case of the issuance of shares of Common
              Stock for consideration in whole or in part other than cash, the
              consideration other than cash shall be deemed to be the Fair
              Market Value thereof; and

                       (3)  In the case of the issuance of options to purchase
              or rights to subscribe for shares of Common Stock, securities by
              their terms convertible into or exchangeable for shares of Common
              Stock, or options to purchase or rights to subscribe for such
              convertible or exchangeable securities (each of which shall be
              deemed to be an issuance of Common Stock hereunder):

                            (a) the aggregate maximum number of shares of Common
                       Stock deliverable upon exercise of such options to
                       purchase or rights to subscribe for Common Stock shall be
                       deemed to have been issued at the time such options or
                       rights were issued and for a consideration equal to the
                       consideration (determined in the manner provided in
                       SUBCLAUSES (1) and (2) above), if any, received by the
                       Corporation upon the issuance of such options or rights
                       plus the minimum purchase price provided in such options
                       or rights for the Common Stock covered thereby;

                            (b) the aggregate maximum number of shares of Common
                       Stock deliverable upon conversion of or in exchange for
                       any such convertible or exchangeable securities or upon
                       the exercise of options to purchase or rights to
                       subscribe for such convertible or exchangeable securities
                       and subsequent conversion or

                                                                            -13-
<Page>

                       exchange thereof shall be deemed to have been issued at
                       the time such securities, options, or rights were issued
                       and for a consideration equal to the consideration
                       received by the Corporation for any such securities and
                       related options or rights (excluding any cash received on
                       account of accrued interest or accrued dividends), plus
                       the additional consideration, if any, to be received by
                       the Corporation upon the conversion or exchange of such
                       securities or the exercise of any related options or
                       rights (the consideration in each case to be determined
                       in the manner provided in SUBCLAUSES (1) and (2) above);

                            (c) on any change in the number or exercise price of
                       shares of Common Stock deliverable upon exercise of any
                       such options or rights or conversions of or exchange for
                       such securities, other than a change resulting from the
                       anti-dilution provisions thereof, the applicable
                       Liquidation Event Conversion Price shall forthwith be
                       readjusted to such Liquidation Event Conversion Price as
                       would have been obtained had the adjustment made upon the
                       issuance of such options, rights or securities not
                       converted prior to such change or options or rights
                       related to such securities not converted prior to such
                       change been made upon the basis of such change; and

                            (d) on the expiration of any such options or rights,
                       the termination of any such rights to convert or exchange
                       or the expiration of any options or rights related to
                       such convertible or exchangeable securities, the
                       applicable Liquidation Event Conversion Price shall
                       forthwith be readjusted to such Liquidation Event
                       Conversion Price as would have been obtained had the
                       adjustment made upon the issuance of such options,
                       rights, securities or options or rights related to such
                       securities been made upon the basis of the issuance of
                       only the number of shares of Common Stock actually issued
                       upon the exercise of such options or rights, upon the
                       conversion or exchange of such securities, or upon the
                       exercise of the options or rights related to such
                       securities and subsequent conversion or exchange thereof.

                  (C)  If, at any time after the applicable Original Issuance
        Date, the number of shares of Common Stock outstanding is increased by

                                                                            -14-
<Page>

        a stock dividend payable in shares of Common Stock or by a subdivision
        or split-up of shares of Common Stock, then, following the record date
        for the determination of holders of shares of Common Stock entitled to
        receive such stock dividend, subdivision or split-up (or if no record
        date is set, the date such stock dividend, subdivision or stock split is
        consummated), the Liquidation Event Conversion Prices shall be
        appropriately decreased so that the number of shares of Common Stock
        issuable on conversion of each share of a particular series of Preferred
        Stock shall be increased in proportion to such increase in outstanding
        shares of Common Stock.

                  (D)  If, at any time after the applicable Original Issuance
        Date, the number of shares of Common Stock outstanding is decreased by a
        combination of the outstanding shares of Common Stock, then, following
        the record date for such combination, the Liquidation Event Conversion
        Prices shall be appropriately increased so that the number of shares of
        Common Stock issuable on conversion of each share of a particular series
        of Preferred Stock shall be decreased in proportion to such decrease in
        outstanding shares of Common Stock.

                  (E)  In the event of any capital reorganization of the
        Corporation, any reclassification of any class or series of capital
        stock of the Corporation (other than a change in par value or from no
        par value to par value or from par value to no par value or as a result
        of a stock dividend or subdivision, split-up or combination of shares of
        capital stock), or any consolidation or merger of the Corporation, each
        share of each series of Preferred Stock shall, after such
        reorganization, reclassification, consolidation or merger, be
        convertible into the kind and number of shares or other securities or
        property of the Corporation or of the corporation resulting from such
        consolidation or surviving such merger to which the holder of the class
        of Common Stock deliverable (immediately prior to the time of such
        reorganization, reclassification, consolidation or merger) upon
        conversion of shares of such series of Preferred Stock would have been
        entitled upon such reorganization, reclassification, consolidation or
        merger. The provisions of this SUBCLAUSE (E) shall similarly apply to
        successive reorganizations, reclassifications, consolidations and
        mergers.

                  (F)  If any event occurs of the type contemplated by the
        provisions of this SECTION 5.3(c)(iv) but not expressly provided for by
        such provisions (including, without limitation, the granting of stock
        appreciation rights, phantom stock rights or other rights with equity
        features, but excluding any issuance of Common Stock Equivalents
        pursuant to any Equity Incentive Plan or Excluded Stock), then the Board
        shall make an appropriate reduction in the Liquidation Event Conversion
        Prices so as to protect the rights of the holders of each series of the
        Preferred Stock.

                                                                            -15-
<Page>

                  (G)  All calculations under this paragraph shall be made to
        the nearest one hundredth (1/100) of a cent.

                  (H)  In any case in which the provisions of this SECTION
        5.3(c)(iv) shall require that an adjustment shall become effective
        immediately after a record date of an event, the Corporation may defer
        until the occurrence of such event (i) issuing to the holder of any
        shares of Preferred Stock converted after such record date and before
        the occurrence of such event the shares of capital stock issuable upon
        such conversion by reason of the adjustment required by such event in
        addition to the capital stock issuable upon such conversion before
        giving effect to such adjustments, and (ii) paying to such holder any
        amount in cash in lieu of a fractional share of capital stock; PROVIDED,
        HOWEVER, that the Corporation shall deliver to such holder an
        appropriate instrument evidencing such holder's right to receive such
        additional shares and such cash.

                  (I)  Whenever the Liquidation Event Conversion Prices shall be
        adjusted as provided in this SECTION 5.3(c)(iv), the Corporation shall
        make available for inspection during regular business hours, at its
        principal executive offices or at such other place as may be designated
        by the Corporation, a statement, signed by its chief executive officer,
        showing in detail the facts requiring such adjustment and the applicable
        Liquidation Event Conversion Price that shall be in effect after such
        adjustment. The Corporation shall also cause a copy of such statement to
        be sent by first class certified mail, return receipt requested and
        postage prepaid, to each holder of Preferred Stock at such holder's
        address appearing on the Corporation's records. Where appropriate, such
        copy may be given in advance and may be included as part of any notice
        required to be mailed under the provisions of CLAUSE (J) below.

                  (J)  If the Corporation shall propose to take any action of
        the types described in CLAUSES (C), (D) or (E) of this SECTION
        5.3(c)(iv), the Corporation shall give notice to each holder of
        Preferred Stock in the manner set forth in CLAUSE (I) above, which
        notice shall specify the record date, if any, with respect to any such
        action and the date on which such action is to take place. Such notice
        shall also set forth such facts with respect thereto as shall be
        reasonably necessary to indicate the effect of such action (to the
        extent such effect may be known at the date of such notice) on the
        applicable Liquidation Event Conversion Price and the number, kind or
        class of shares or other securities or property which shall be
        deliverable or purchasable upon the occurrence of such action or
        deliverable upon conversion of Preferred Stock. In the case of any
        action which would require the fixing of a record date, such notice
        shall be given at least 10 days prior to the date so fixed, and in case
        of all other action, such notice shall be given at least 10 days prior
        to the taking of such proposed action. Failure to give such notice, or
        any defect therein, shall not affect the legality or validity of any
        such action.

                                                                            -16-

        (d) LIQUIDATION.

              (i) SERIES A PREFERRED STOCK. Upon the consummation of any
     Liquidation Event, prior to payment of the Class A Common Liquidation
     Preference Amount, the Common Liquidation Preference Amount and the Series
     B Liquidation Preference Amount, the holders of Series A Preferred Stock
     shall be entitled to receive, out of the proceeds of such Liquidation
     Event, an amount per share of Series A Preferred Stock equal to the greater
     of (i) the Original Cost of such share (the "SERIES A PREFERRED LIQUIDATION
     PREFERENCE AMOUNT") and (ii) the amount such holder would have received if
     such share of Series A Preferred Stock had been converted into Class A
     Common Stock immediately prior to such Liquidation Event. If upon the
     consummation of any Liquidation Event the proceeds of such Liquidation
     Event are insufficient to pay the holders of Series A Preferred Stock the
     full Series A Preferred Liquidation Preference Amount, the holders of
     Series A Preferred Stock shall share ratably in any distribution of
     proceeds based upon the number of shares of Series A Preferred Stock held
     by each such holder. Anything contained in this SECTION 5.3 to the contrary
     notwithstanding, each holder of Series A Preferred Stock shall have the
     right to convert all or any part of the shares of Series A Preferred Stock
     held by such holder into shares of Class A Common Stock pursuant to SECTION
     5.3(c)(i) in lieu of receiving the Series A Preferred Liquidation
     Preference Amount in connection with any Liquidation Event.

             (ii) SERIES B PREFERRED STOCK. Upon the consummation of any
     Liquidation Event, PARI PASSU with the Common Liquidation Preference Amount
     but after payment of the Series A Liquidation Preference Amount and the
     Class A Common Liquidation Preference Amount, the holders of Series B
     Preferred Stock shall be entitled to receive, out of the proceeds of such
     Liquidation Event, an amount per share of Series B Preferred Stock equal to
     the greater of (i) the Original Cost of such share (the "SERIES B PREFERRED
     LIQUIDATION PREFERENCE AMOUNT") and (ii) the amount such holder would have
     received if such share of Series B Preferred Stock had been converted into
     Common Stock immediately prior to such Liquidation Event. If upon the
     consummation of any Liquidation Event the proceeds of such Liquidation
     Event are insufficient to pay the holders of Series B Preferred Stock the
     full Series B Preferred Liquidation Preference Amount, the holders of
     Series B Preferred Stock shall share ratably in any distribution of
     proceeds together with the holders of Common Stock in accordance with
     SECTION 5.2(d). Anything contained in this SECTION 5.3 to the contrary
     notwithstanding, each holder of Series B Preferred Stock shall have the
     right to convert all or any part of the shares of Series B Preferred Stock
     held by such holder into shares of Common Stock pursuant to SECTION
     5.3(c)(iii) in lieu of receiving the Series B Preferred Liquidation
     Preference Amount in connection with any Liquidation Event.

                                                                            -17-

        (e) OPTIONAL REDEMPTION UPON A QPO.

              (i) Not less than ten (10) days and not more than thirty (30) days
     prior to the Target QPO Date, the Corporation shall deliver, in accordance
     with SECTION 5.3(e)(ii), an offer (the "QPO OFFER") to redeem the then
     outstanding shares of Preferred Stock at the applicable QPO Redemption
     Price, payable in accordance with the procedures set forth in this SECTION
     5.3(e). The Requisite Series A Preferred Holders and the Requisite Series B
     Preferred Holders (voting separately as a class with respect to their
     respective series of Preferred Stock) shall have the right to require that
     the Corporation redeem any or all of the then outstanding shares of Series
     A Preferred Stock and Series B Preferred Stock, respectively, upon the
     consummation of a QPO, at the applicable QPO Redemption Price of such
     shares by giving written notice to the Corporation of such election within
     three business days following delivery of the QPO Offer Notice by the
     Corporation; PROVIDED, HOWEVER, that, if the managing underwriter in the
     QPO advises the Corporation that the redemption of the Series B Preferred
     Stock would adversely affect the successful offering and sale (including
     pricing) of the shares to be sold in the QPO, then such shares of Series B
     Preferred Stock to be redeemed pursuant to this SECTION 5.3(e)(i) shall be
     converted into Common Stock in accordance with SECTION 5.3(c)(ii).

             (ii) Within the period set forth in SECTION 5.3(e)(i), the
     Corporation shall send by nationally-recognized overnight courier or by
     first class mail, postage prepaid, to each holder of Preferred Stock, at
     the address for such holder appearing in the register maintained by or on
     behalf of the Corporation, a notice (a "QPO OFFER NOTICE") stating upon the
     election of the Requisite Series A Holders and/or the Requite Series B
     Holders, as applicable:

                  (A)  that a QPO Offer is being made pursuant to this SECTION
        5.3(e) and that all shares of Series A Preferred Stock and, subject to
        the proviso set forth in SECTION 5.3(e)(i), all shares of Series B
        Preferred Stock will be accepted for redemption;

                  (B)  the QPO Redemption Price and the Target QPO Date;

                  (C)  that the holders of Preferred Stock to be redeemed
        pursuant to this SECTION 5.3(e) shall surrender their certificates
        representing shares of Preferred Stock to the Corporation at the address
        specified in the QPO Offer Notice prior to the close of business on the
        business day immediately preceding the QPO Payment Date;

                  (D)  that, with respect to any shares of Preferred Stock to be
        redeemed pursuant to this SECTION 5.3(e), on and after the QPO Payment
        Date (or, if the Corporation defaults in the payment on such date of the
        QPO Redemption Price for any shares of Preferred Stock validly tendered
        pursuant to the QPO Offer, on and after the date such default is cured),
        to the extent permitted by Applicable Law, (x) all other rights with
        respect to

                                                                            -18-
<Page>

        such shares, except the right to receive the QPO Redemption Price, shall
        cease and terminate, (y) such shares shall no longer be deemed to be
        outstanding as of the QPO Payment Date; and

                  (E)  any other reasonable procedures that the holders of
        Preferred Stock must follow to accept a QPO Offer.

            (iii) The Corporation will comply with any securities laws and
     regulations to the extent such laws and regulations are applicable to the
     redemption of the Preferred Stock in connection with a QPO Offer. Without
     limiting the foregoing, in the event that a QPO occurs and the Requisite
     Series A Holders and/or Requisite Series B Holders exercise their
     respective rights to require the Corporation to redeem shares of Preferred
     Stock pursuant to this SECTION 5.3(e), if such redemption constitutes a
     "tender offer" for purposes of Rule 14e-1 under the Exchange Act at that
     time, the Corporation will comply with the requirements of Rule 14e-1 as
     then in effect with respect to such redemption.

             (iv) On the QPO Payment Date, the Corporation shall, (i) to the
     extent lawful, accept for redemption the number and series of shares of
     Preferred Stock validly tendered pursuant to the QPO Offer and (ii)
     promptly deliver to each holder of Preferred Stock redeeming shares of
     Preferred Stock pursuant to this SECTION 5.3(e) by wire transfer of
     immediately available funds the QPO Redemption Price therefor. With respect
     to any shares of Preferred Stock to be redeemed pursuant to this SECTION
     5.3(e), on and after the QPO Payment Date (or, if the Corporation defaults
     in the payment on such date of the QPO Redemption Price for any shares of
     Preferred Stock validly tendered pursuant to the QPO Offer, on and after
     the date such default is cured), to the extent permitted by Applicable Law,
     (x) all other rights with respect to such shares, except for the right to
     receive payment of the QPO Redemption Price, shall cease and terminate, and
     (y) such shares shall no longer be deemed to be outstanding as of the QPO
     Payment Date.

              (v) The payment of the QPO Redemption Price shall be subject to
     and made only in accordance with the terms and provisions of any agreement
     or instrument governing any indebtedness of the Corporation or any of its
     subsidiaries that restricts the Corporation's ability to pay the QPO
     Redemption Price (or restricts the Corporation's subsidiaries from
     distributing sufficient funds to the Corporation to make such payment) on
     the QPO Redemption Date; PROVIDED, HOWEVER, that, in the event of such
     restriction, the Corporation (and to the extent applicable, its
     subsidiaries) shall use their respective commercially reasonable efforts to
     (i) obtain the necessary consents or waivers from the requisite holders of
     such indebtedness to make the QPO Redemption Payment or (ii) obtain
     financing to permit the payment of the QPO Redemption Price.

             (vi) Without prejudice to any other rights any holder of Preferred
     Stock may have upon failure by the Corporation to redeem all shares of
     Preferred Stock validly tendered by such holder pursuant to the QPO Offer,
     if the

                                                                            -19-
<Page>

     Corporation redeems less than all of the shares of Preferred Stock validly
     tendered, then the Corporation shall redeem those shares of Preferred Stock
     validly tendered from the holders thereof out of funds legally available
     therefor ratably based upon the number of shares of Preferred Stock that
     each holder of Preferred Stock has validly tendered pursuant to the QPO
     Offer, until all of such shares of Preferred Stock validly tendered have
     been redeemed. The Corporation shall redeem any validly tendered but
     unredeemed shares of Preferred Stock as soon as practicable after the
     Corporation has funds legally available therefor.

5.4  CONVERSION MECHANICS.

        Each conversion of shares of any class or series of capital stock of the
Corporation into shares of another class or series of capital stock of the
Corporation shall be effected by the surrender of the certificate or
certificates representing the shares of stock to be converted (the "CONVERTING
SHARES") at the principal office of the Corporation (or such other office or
agency of the Corporation as the Corporation may designate by written notice to
the holders of such class or series of capital stock) at any time during its
usual business hours, together with written notice by the holder of such
Converting Shares, stating that such holder desires to convert the Converting
Shares, or a stated number of the shares represented by such certificate or
certificates, into the number of shares of the class or series into which such
shares may be converted (the "CONVERTED SHARES") pursuant to the terms of this
Certificate of Incorporation. Such notice shall also state the name or names
(with addresses) and denominations in which the certificate or certificates for
Converted Shares are to be issued and shall include instructions for the
delivery thereof. Promptly after such surrender and the receipt of such written
notice of conversion, the Corporation will issue and deliver in accordance with
the surrendering holder's instructions the certificate or certificates
evidencing the Converted Shares issuable upon such conversion, and the
Corporation will deliver to the converting holder a certificate (which shall
contain such legends as were set forth on the surrendered certificate or
certificates and which shall otherwise be required by the Stockholders'
Agreement or Applicable Law) representing any shares which were represented by
the certificate or certificates that were delivered to the Corporation in
connection with such conversion, but which were not converted. Such conversion,
to the extent permitted by Applicable Law, shall be deemed to have been effected
as of the close of business on the date on which such certificate or
certificates shall have been surrendered and such notice shall have been
received by the Corporation, and at such time the rights of the holder of the
Converting Shares as such holder shall cease and the person or persons in whose
name or names the certificate or certificates for the Converted Shares are to be
issued upon such conversion shall be deemed to have become the holder or holders
of record of the Converted Shares. Upon issuance of shares in accordance with
this SECTION 5.4, such Converted Shares shall be deemed to be duly authorized,
validly issued, fully paid and non-assessable, with no personal liability
attaching to the ownership thereof and free from all taxes, liens or charges
with respect thereto due to any action of the Corporation. The Corporation shall
take all such actions as may be necessary to assure that all such shares may be
so issued without violation of any Applicable Law or any requirements of any
securities exchange upon which such shares may be listed (except for official
notice of issuance, which will be immediately transmitted by the Corporation
upon issuance).

                                                                            -20-
<Page>

The Corporation shall not close its books against the transfer of shares in any
manner which would interfere with the timely conversion of any shares. The
issuance of certificates for shares of any class or series of capital stock
(upon conversion of shares of any other class or series of capital stock or
otherwise) shall be made without charge to the holders of such shares for any
issuance tax in respect thereof or other cost incurred by the Corporation in
connection with such conversion and/or the issuance of such shares; PROVIDED,
HOWEVER, that the Corporation shall not be required to pay any tax which is or
may be payable in respect of any transfer involved in the issuance and delivery
of any certificate in a name other than that of the holder of the shares
converted. No fractional shares of capital stock or scrip shall be issued upon
conversion of any shares. The number of full shares issuable upon conversion
shall be computed on the basis of the aggregate number of shares to be converted
by a holder. Instead of any fractional shares which would otherwise be issuable
upon conversion of capital stock, the Corporation shall pay a cash adjustment in
respect of such fractional interest in an amount equal to the product of (i) the
Fair Market Value of one share of capital stock and (ii) such fractional
interest. The holders of fractional interests shall not be entitled to any
rights as stockholders of the Corporation in respect of such fractional
interests. The foregoing provisions of this SECTION 5.4 shall apply, as
applicable, to a mandatory conversion of shares of capital stock pursuant to the
reclassification provisions of SECTION 5.1, SECTION 5.2(c)(ii) or SECTION
5.3(c)(ii), PROVIDED that, the failure of the Corporation or any holder of such
shares to comply with such provisions shall not affect the automatic conversion
of such shares pursuant to the applicable Section herein.

5.5  NO REISSUANCE OF PREFERRED STOCK.

     No share or shares of Preferred Stock acquired by the Corporation by reason
of redemption, purchase, conversion or otherwise shall be reissued and all such
shares shall be cancelled, retired or eliminated from the shares which the
Corporation shall be authorized to issue.

5.6  RESERVATION, REGISTRATION AND REPLACEMENT OF STOCK.

        (a) RESERVATION OF SHARES. The Corporation shall (and the stockholders
of the Corporation shall cause the Corporation to) at all times reserve and keep
available out of its authorized but unissued shares of each class or series of
capital stock or its treasury shares, solely for the purpose of issuance upon
the conversion of shares of any other class or series of capital stock
hereunder, such number of shares of such class or series as are then issuable
upon the conversion of all outstanding shares of such other class or series
which may be converted.

        (b) REGISTRATION OF TRANSFER. The Corporation shall keep at its
principal office (or such other place as the Corporation reasonable designates)
a register for the registration of shares of each class or series of its capital
stock. Upon the surrender of any certificate representing shares of any class or
series of capital stock at such place, the Corporation shall, at the request of
the registered holder of such certificate, execute and deliver a new certificate
or certificates in exchange therefor representing in the aggregate the number of
shares of such class or series represented by the surrendered certificate,

                                                                            -21-
<Page>

and the Corporation forthwith shall cancel such surrendered certificate. Each
such new certificate will represent such number of shares of such class or
series as is requested by the holder of the surrendered certificate and will be
substantially identical in form to the surrendered certificate. Subject to any
other restrictions on transfer to which such holder or such shares may be bound,
the Corporation will also register such new certificate in such name as
requested by the holder of the surrendered certificate.

        (c) REPLACEMENT OF CERTIFICATES. Upon receipt of evidence reasonably
satisfactory to the Corporation (an affidavit of the registered holder will be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing one or more shares of any class or series of capital
stock, and (1) in the case of any such loss, theft or destruction, upon receipt
of indemnity reasonably satisfactory to the Corporation (PROVIDED that, if the
holder is a financial institution or other institutional investor, its own
agreement will be satisfactory), or (2), in the case of any such mutilation,
upon surrender of such certificate, the Corporation shall (at its expense)
execute and deliver a new certificate representing such number of shares of such
class or series represented by such lost, stolen, destroyed or mutilated
certificate and dated the date of such lost, stolen, destroyed or mutilated
certificate.

                                   ARTICLE VI

                                    DIRECTORS

        The number of directors of the Corporation shall be such as from time to
time shall be fixed in the manner provided in the By-laws of the Corporation.
The election of directors of the Corporation need not be by ballot unless the
By-laws so require. Any director or any officer elected or appointed by the
stockholders or by the Board of Directors may be removed at any time in such
manner as shall be provided in the By-laws of the Corporation and the
Stockholders' Agreement.

        A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived any improper personal benefit. If
the DGCL is amended after the date of this Certificate of Incorporation to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the DGCL, as
so amended.

        The Corporation shall, to the fullest extent permitted by Section 145 of
the DGCL, as the same may be amended and supplemented from time to time,
indemnify any and all persons whom it shall have the power to indemnify under
said section from and against any and all of the expenses, liabilities or other
matters referred to in or covered by said section, and the indemnification
provided for herein shall not be deemed exclusive of any other rights to which
those indemnified may be entitled under any By-Law,

                                                                            -22-
<Page>

agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

        Any repeal or modification of the foregoing two paragraphs by the
stockholders of the Corporation shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification.

                                   ARTICLE VII

                                   AMENDMENTS

        From time to time any of the provisions of this Certificate of
Incorporation may be altered, amended or repealed, and other provisions
authorized by Applicable Law may be added or inserted, in the manner and at the
time prescribed by said Applicable Law, and all rights at any time conferred
upon the stockholders of the Corporation by this Certificate of Incorporation
are granted subject to the provisions of this ARTICLE VII.

                                  ARTICLE VIII

                                     NOTICES

        All notices referred to herein shall be in writing, shall be delivered
personally or by overnight courier and shall be deemed to have been given when
so delivered or sent by overnight courier to the Corporation at its principal
executive officers and to any stockholder of the Corporation at such
stockholder's address as it appears in the stock records of the Corporation
(unless otherwise specified in a written notice to the Corporation by such
stockholder).
